A Nonlinear Enhanced Microresonator Gyroscope [PDF]

Conference on Lasers and Electro-Optics, 2017
It has been theoretically predicted in the 1980s that an optical ring resonator with Kerr nonlinearity that is pumped equally in both directions exhibits spontaneous symmetry breaking [I], in which light of a given frequency can only propagate in one direction.

Dispersion Engineering of Silicon Nitride Microresonators via Reconstructable SU-8 Polymer Cladding

Micromachines, 2022
In this work, we propose a novel way to flexibly engineer the waveguide dispersion by patterning the cladding of waveguide microresonators. Experimentally, we demonstrate silicon nitride waveguides with air-, oxide-, and SU-8 polymer-cladding layers and ...

Soliton blockade in bidirectional microresonators [PDF]

Optics Letters, 2020
We report a method to control, disrupt, and restore a regime of unidirectional soliton generation in a bidirectionally pumped ring microresonator. This control, i.e., the soliton blockade, is achieved by tuning the pump frequency of the counterrotating field. The blockade effect is correlated with the emergence of a dark–bright

Flexible microresonators: lasing and sensing [PDF]

SPIE Proceedings, 2014
Microresonators have drawn a great deal of interest for their importance in both practical applications and fundamental physics in light-matter interaction. The optical confinement provided by a microresonator greatly enhances the interaction between optical spatial mode and the light emitting materials.

Numerical Study of Resonant Optical Parametric Amplification via Gain Factor Optimization in Dispersive Microresonators

Photonics, 2019
The achievement of wideband high-gain optical parametric amplification has not been shown in micrometer-scale cavities. In this paper we have computationally investigated the optical parametric amplification process in a few micrometer-long dispersive ...

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs

Laser &Photonics Reviews, EarlyView.
The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...
